Is it possible to form a triangle whose sides are 3.5 cm 4.5 cm 7.5 cm long?
A triangle can be formed with the side length of 3.5 cm, 4.5 cm and 7.5 cm.
The one side of the triangle should always measure lower than the sum of remaining two sides of triangle. Based on this concept, let's check the sum and compare it with remaining side to find the possibility of triangle construction.
Side a + side b > side c
3.5 + 4.5 > 7.5
Adding the digits
8 > 7.5
Side b + side c > side a
4.5 + 7.5 > 3.5
Adding the digits
12 > 3.5
side c + side a > side b
3.5 + 7.5 > 4.5
Adding the digits
11 > 4.5
The sums are always greater than remaining side based on the mentioned lengths. Thus, the triangle can be formed.

Stella bought 6 packages of balloons. Each package has 15 balloons in it.
Which TWO number sentences could be used to find the total number of balloons Stella bought?
Answers:
(6×10)+(6×5)
6×10+56
(3×10)+(6×5)
(15×3)+(15×3)
6+15
Answer:
"Choices A & D": (6 x 10) + (6 x 5). & (15 x 3) + (15 x 3) are the correct number sentences.
Step-by-step explanation:
1. How many balloons are there in total?The total amount of balloons can be found via cross-multiplication. To cross-multiply fractions, we multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction.If one package has 15 balloons, how many balloons do 6 packages have?:[tex]\frac{1 package}{6 packages} = \frac{15 balloons}{X balloons}[/tex][tex]\frac{1 package xX balloons}{1 package} = \frac{6 packages x 15 balloons}{1 package}[/tex][tex]6 x 15 balloons = 90 balloons.[/tex]So now we know there are 90 balloons in 6 packages. 2. PEMDASPEMDAS states to complete the operations on numbers in the order that the letters appear.1. Parentheses, ie. (6 + 10) - (11 x 5).
2. Exponents, ie. [tex]a^{c}[/tex].
3. Division, ie. 11÷5.
4. Addition, ie. 12+1.
5. Subtraction, ie. 10-5.
3. Find the TWO NUMBER SENTENCES that can be evaluated to 90.Number Sentences:
a. (6 x 10) + (6 x 5).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 6 x 10 = 60.
iii. 6 x 5 = 30.
iv. Then we add the products.
v. 60 + 30 = 90.
vi. So this choice IS CORRECT.
b. 6 x 10 + 5.
According to PEMDAS. We multiply first.ii. 6 x 10 = 60.
iii. Then we add the product to 5.
iv. 60 + 5 = 65.
v. 65 DOES NOT equal 90 so this is one of the incorrect number sentences.
c. (3 x 10) + (6 x 5).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 3 x 10 = 30.
iii. 6 x 5 = 30.
iv. Then we add the products.
v. 30 + 30 = 60.
vi. 60 DOES NOT equal 90 so this is one of the incorrect number sentences.
d. (15 x 3) + (15 x 3).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 15 x 3 = 45.
iii. 15 x 3 = 45.
iv. Then we add the products.
v. 45 + 45 = 90.
vi. So this choice IS CORRECT.
e. 6 + 15.
i. 6 + 15 = 21.
ii.21 DOES NOT equal 90 so this is one of the incorrect number sentences.
4. (6 x 10) + (6 x 5). & (15 x 3) + (15 x 3). These are the correct number sentences.Please let me know if this helped (photo also attached)!!!
What is the graph of the system Y â 2x 3 and 2x 4y â 8?
The graph of the system of equations y = -2x + 3 and 2x + 4y = 8 is a pair of straight lines passing through the points (2/3, 5/3).
y = -2x + 3 …. (1)
2x + 4y = 8 …. (2)
Substitute eqn (1) in (2)
2x + 4 (-2x + 3) - 8 = 0
Using the multiplicative distributive property, we get
2x - 8x + 12 = 8
By rearranging the above eqn, we get
2x - 8x = 8 - 12
-6x = - 4
Dividing both sides by -2, we get
3x = 2
x = 2/3
Put the value of x in eqn (1)
y = -2 (2/3) + 3
y = -4/3 + 3
y = (-4 + 9)/3
y = 5/3

There are only blue counters, red counters and green counters in a box.
Sam and harry are family. Sam is currently five times harry's age. Sam's age is also 10 more than three times harry's age. The following system of equations models this scenario: x = 5y x = 10 + 3y what are their current ages? sam is 25 years old, and harry is 5 years old. Sam is 30 years old, and harry is 6 years old. Sam is 35 years old, and harry is 7 years old. Sam is 40 years old, and harry is 8 years old.
Sam is 25 years old, and Harry is 5 years old.
If we multiply the age of Harry (5) five times, it will give us 25:
5×5= 25
and if we multiply Harry's age three times and then add up ten, it will give us 25:
(5×3) +10 = 25
15 + 10 = 25
25 = 25

$45 and left-handed gloves cost $50. How
many right-handed gloves were sold?
Based on the estimates above, they sold 3 left-handed and 17 right-handed gloves.
Howmany right-handed gloves were sold?17 right-handed gloves and 3 left-handed gloves were sold.
We must create a set of equations to address this issue.
The total number of gloves sold was 12, and the total income was 940.
Gloves for the right hand (x) = 45.
gloves for the left hand (y) = 50.
Equations x+y=20...
45x + 50y = 561 is the first equation (ii)
Equation derived from equation I x + y = 12 – y (iii)
Equation (ii) becomes 45x + 50y = 940
by substituting equation (iii):
x = 12 - u 45
(12 - y) + 50y = 940;
540 - 45y + 50y = 940;
540 + 7y = 561;
7y = 21 y = 3

Find the nonzero value() of k that will caue the equation to have the given number and type of olution. Kx2−2x4=0, 2 real olution
The polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.
The equation kx^2 - 2x^4 = 0 has the form of a polynomial equation, where k and x are variables. To find the nonzero value of k that will cause the equation to have 2 real solutions, we need to analyze the roots of the equation.
The roots of the equation are the values of x that make the equation equal to zero. To find the roots, we can set each factor of the polynomial equal to zero and solve for x:
kx^2 = 0 and 2x^4 = 0
The first equation gives us x = 0, which is not a valid solution, because it is not a real number.
The second equation gives us x^4 = 0, then x = 0. But x = 0 is not a valid solution for this equation, as it is not a real number.
Therefore, the polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.

What is Internal angles?The internal angle formed by a closed polygon's sides inside of itself. A shape's interior can contain angles. The closed, side-and-vertex-containing shapes are known as polygons. All of the internal angles of a regular polygon are equal. For instance, the inner angles of a square are all exactly 90 degrees, or the right angle. Triangles always have three inner angles that add up to 180 degrees.

Which list gives the sample space for pulling 2 marbles from the bag with replacement?
List 1
List 2
List 3
List 4
The list that gives the sample space for pulling 2 marbles from the bag with replacement is given as follows:
List 4.
What is a sample space?A sample space is a set that contains all possible outcomes in the context of an experiment.
The fact that the experiment is with replacement means that for each of the two marbles, there are two possible outcomes.
Then, applying the Fundamental Counting Theorem, the total number of outcomes is given as follows:
4 x 4 = 16.
This means that the correct list is either the list 3 or the list 4.
As there is replacement, it is possible to take two purple marbles, even though there is only one purple marble, as the same can be taken with replacement, and thus the correct list is given by list 4.
